lmngr: Geary Non Normality Lagrange Multiplier Runs Test

+--------+ ----+ Syntax +-----------------------------------------------------------

lmngr depvar indepvars [if] [in] [weight] , [ noconstant vce(vcetype) ]

+---------+ ----+ Options +----------------------------------------------------------

noconstant suppress constant term

SE/Robust vce(vcetype) vcetype may be ols, robust, cluster clustvar, bootstrap, jackknife, hc2, or hc3

+-------------+ ----+ Description +------------------------------------------------------

lmngr computes Geary Lagrange Multiplier non normality runs test for OLS residuals after regress command.

Ho: Error has normality distribution. Ha: Error has non normality distribution.

Geary LM test has degrees of freedom with chi2 at 2 DF (5.99).

+---------------+ ----+ Saved Results +----------------------------------------------------

lmngr saves the following in r():

Scalars r(lmn) Geary LM Test r(df) Chi2 degrees of freedom r(p) P-Value significance

+---------+ ----+ Example +----------------------------------------------------------
